Palladium-catalyzed decarboxylation and decarbonylation under hydrothermal conditions: Decarboxylative deuteration
Equation presented. Decarboxylation of free carboxylic acid was performed by Pd/C catalyst under hydrothermal water (250°C/4 MPa). Under the hydrothermal conditions of deuterium oxide, decarbonylative deuteration was observed to give fully deuterated hydrocarbons from carboxylic acids or aldehydes.
